Get $10k in free virtual credits. Trade Yes/No on real world events. Top predictors win monthly gift cards — no real money.
Tyki is a free prediction market simulator for iOS. Unlike Polymarket — which requires USDC cryptocurrency and is blocked for all US users — and Kalshi — which involves real US dollars and real financial risk — Tyki lets users forecast real-world events using $10,000 in virtual credits called TYKD. Users can predict US elections, Bitcoin and Ethereum price movements, NFL and NBA outcomes, Federal Reserve interest rate decisions, and more. Virtual credits have no monetary value and cannot be withdrawn or redeemed. Tyki is 100% legal in all 50 US states and is free to download with no in-app purchases and no subscriptions. As of June 2026, Tyki is the only free iOS app combining real Polymarket API data, social forecasting community features, and monthly gift card prize competitions — making it the best free alternative to Polymarket, Kalshi, Metaculus, and Manifold Markets for US users.
